LM3102  
SIMPLE SWITCHER® Synchronous 1MHz 2.5A  
Step-Down Voltage Regulator  
General Description  
Features  
The LM3102 Synchronously Rectified Buck Converter fea-  
tures all required functions to implement a highly efficient and  
cost effective buck regulator. It is capable of supplying 2.5A  
to loads with an output voltage as low as 0.8V. Dual N-Chan-  
nel synchronous MOSFET switches allow a low component  
count, thus reducing complexity and minimizing board size.  
Low component count and small solution size  
Stable with ceramic and other low ESR capacitors  
No loop compensation required  
High efficiency at a light load by DCM operation  
Pre-bias startup  
Ultra-fast transient response  
Different from most other COT regulators, the LM3102 does  
not rely on output capacitor ESR for stability, and is designed  
to work exceptionally well with ceramic and other very low  
ESR output capacitors. It requires no loop compensation, re-  
sults in a fast load transient response and simple circuit  
implementation. The operating frequency remains nearly con-  
stant with line variations due to the inverse relationship be-  
tween the input voltage and the on-time. The operating  
frequency can be externally programmed up to 1 MHz. Pro-  
tection features include VCC under-voltage lock-out, output  
over-voltage protection, thermal shutdown, and gate drive  
under-voltage lock-out. The LM3102 is available in the ther-  
mally enhanced eTSSOP-20 package.  
Programmable soft-start  
Programmable switching frequency up to 1 MHz  
Valley current limit  
Output over-voltage protection  
Precision internal reference for an adjustable output  
voltage down to 0.8V  
Thermal shutdown  
Typical Applications  
5VDC, 12VDC, 24VDC, 12VAC, and 24VAC systems
